The ADC121S021 from Texas Instruments is a low-power, single-channel CMOS 12-bit analog-to-digital converter with a successive-approximation register (SAR) architecture. It is fully specified over a sample rate range of 50 ksps to 200 ksps, offering variable power management that scales with the conversion rate.
Key electrical specifications include a typical signal-to-noise ratio (SNR) of 72.3 dB, differential non-linearity (DNL) of -0.25/+0.45 LSB, and integral non-linearity (INL) of -0.4/+0.45 LSB. Power consumption is typically 1.5 mW at a 3.6 V supply and 7.9 mW at 5.25 V. The device operates from a single analog and digital supply voltage ranging from 2.7 V to 5.25 V.
The converter includes an internal track-and-hold circuit and outputs straight binary serial data. It is compatible with SPI, QSPI, MICROWIRE, and common DSP serial interfaces. The ADC121S021 is available in a 6-WDFN exposed pad package (6-WSON, 2.2x2.5 mm) and is designed for surface mount assembly. It operates over a temperature range of -40°C to 85°C.
